7.7 Differential Driver Switching Characteristics (Low Speed Mode)

over recommended ranges of operating free-air temperature and supply voltage, CL = 50 pF (unless otherwise noted)
PARAMETER TEST CONDITIONS MIN MAX UNIT
tr Transition rise time for DP or DM(1) CL = 200 pF to 600 pF, See Figure 1 and Figure 2 75 300 ns
tf Transition fall time for DP or DM(1) CL = 200 pF to 600 pF, See Figure 1 and Figure 2 75 300 ns
t(RFM) Rise/fall time matching(1) (tr/tf) × 100 80% 120%
VO(CRS) Signal crossover output voltage(1) CL = 200 pF to 600 pF 1.3 2.0 V
